Figure 1 represents, inside elevation, a handtacking machine embodying the invention PATENT V -onnntnslwaetrobn LYNN, MASSACHUSETTS, i

sachusetts, ,have invented an Inn ofwhich the-follovvifigisa specification:

in a hand-operated machine.

for boots and shoes, nd is showm'e ibodied comb-like tack-strip of indefinite length, properly sustainedina strip-guide, andfed automatically to the cutting mechanism and driver.

The invention has reference to the combination, with the-head in which the driver operates, of a strip-guide placed at an acute angle with reference to the path of the driver, and with such relation to the tack-cutting mechanism that the body of the tack to be cut from the strip and to be driven by the driver is so'removed from the adjacent connected tack of the strip that it is made to occupy a position substantially in line with the driver, whereas the other tacks of the strip stand at an angle thereto. This change of position of the body of the tack to be cut and driven from the position and inclination of the adjacent tack of the strip bends the headforming portion of the strip between adjacent The cutter or knife is made triangular or web-shaped in cross-section& Bymeans of delivering the strip at an angle to the driverpassage, it is possible to make the knife quite thick at its base, and, consequently, very strong. The verticalside of the knife bears against the tack being cut from the strip to be driven,

and the inclined face, corresponding to the hypotenuse of the triangle, bears against the edge of the tack next to be fed forward under herein described; Fig. 2, a rear side view;

ed withtwo guides, b -c--o'ne, offor the tackdriving bar '01, and the other for "the slide-bar "e, "that operates-the carrier f andthe attached cutter or knife'g. The driver bar is provided,

1 as"u'sual, with a nail or tack drivingrod, This invention relates tov tacking-machines "adapted to ,drivethe head orlupper end'of the i -tackl'out through the usual opening in the nail tube or foot h, preferably serrated orrough- The tacks to be driveu'are' s v'ered from a" ened at its lower end. The driving bar (Z is connected with the bar 6 by means of a lever, 01, having its fulcrum at j. When one bar is driven or forced down, the lever will raise the other. The bar 0 has at its lower end apin, 1, that extends into an irregular slot, m, made in the carrier f, adapted to slide, in suitable ways formed in the head. The knife g, adjustably attached to the carrier, has a vertical face, 1, an inclined face, 2, and a cutting-edge, 3.

The tack-strip n is held in a strip-guide, 0, attached to the head, so as to present the headforming portion of the strip to the path of the nail-driver in an acute-angular direction. The follower 1), connected with the elastic cord or spring 1*, attached to the strip-guide at s, rests against the outer end of the comb-like tackstrip, and moves the end or head forming portion of the tack-strip against one wall of the driver passage, when permitted so to do by the removal of the knife.

The head-forming part of the tack at the end of the strip, held forward against the wall of the driver-passage, stands at an inclination to the driver-passage, as shown in Fig. 7; but when the knife is moved forward, its thin wedge-shaped end or, having an inclination -corresponding with the opening between the adjacent tacks, as shown in Fig. 6, enters between the tack having its head stopped by the wall of the nail-passage and the adjacent tack of the strip, and removes the body of the tack from an inclined to a vertical position, as shown'in Fig. 8, it then being in line with the nail-passage. In this position the knife separates the first tack of the strip from the second, and forms one side of the driver-passage. Lying between adjacent tacks, the upper edge 3 of the knife becomes the lower member of the severing mechanism for the driver acting as the upper or second This change of position of the body head, the member.

of the tack with reference to the remaining tacks cf the strip assists in severing the headforming portion, enables the knife to be made very strong, and the head to be cut 011" squarely.

It is evident that the acuteness of the angle of the strip-guide with reference t0 the driver may be changed, and instead of the inclined guide we might use a guide somewhat curved.

The knife is thicker at its base than the usual distance 0f the point of one tack from the adjacent tack when the strip is in its normal condition. This thickened base separates the points of the adjacent nails, and "bends the headforming portion of the tack-strip be tweenadjacent nails before; severing a nail fromthe strip The point of the knife being beveled, as described, gradually removes the tack from its normal position with referenceto the other tacks of the strip to a position in iinewith the driver-passage.

. This wedge-pointedknife with thickened base is, therefore, an important requisite of this invention.

i; In atackiiig-inachine the privatisation, with a strip guide or holder, of a longitudinally-reciprocating wedge-pointed triangular knife, adapted to remove the body of the tack to be driven from the direction of the body of the adjacent of thestri before severing the tack from the strip and driving it, substantially as described.
